Sonic and Tails escape outrun a dinosaur

'Never mind that now, encyclopedia-brain! Run away! Run away very fast!' shouted Sonic. The approaching monster was coming towards them, teeth bared, its eyes glinting in the bright sunlight, its enormous legs eating up the distance that separated it from the troubled two heroes as they turned and sprinted away.
Tails took an early lead, but within seconds Sonic had passed him, his red shoes whipping through the long grass as he hurtled towards the nearest patch of forest. 'Into the trees!' he shouted over his shoulder. 'It won't be able to follow us in there!'
Tails did not need a second warning; he changed his direction and steered his way towards the enormous trees. Behind him he could hear the heavy footfalls of the enormous beast as it charged after them, its heavy breath hot and foul on the back of their necks. Tails knew that he was the second fastest creature in the Green Hill Zone, but he had never raced against anything as big as this Utahraptor. Its legs alone were ten times as high as he was, and it was getting closer with every massive step. No wonder the other dinosaur had scarpered so fast.
Tails leaped a bush of brambles and shot into the undergrowth of the forest area. 'Safe!' he exclaimed, slowing down to look back and up at the massive lizardoid as it stood at the edge of the woods, foxed by the thick barrier of trees in its way.
